This 12V Max random orbit sander is designed to tackle hard-to-reach work areas with power and control. It features a well-balanced ergonomic palm grip, which allows your hand to be closest to the work material to avoid tilting and pressing down, for best results. The easy-to-reach on/off switch offers intuitive operation. The Bosch GEX12V-5 Brushless 5 In. Random Orbit Sander has a powerful 12V Max brushless motor, and it is engineered for professional applications. The speed selector delivers best results in different materials and applications. The sander has a 5 In. 8-hole sanding pad, which provides optimal dust collection when the sander is attached to a vacuum or a dust bag. The dust pad is ideal for both flat and concave/convex surfaces. The included dust bag allows mobile dust collection, while the tool has an interface for vacuum hose attachment. It also has soft-start technology, constant speed and a hook-and-loop backing pad. The sander has a compact shape with close-to-the-workpiece design for control in hard-to-reach areas.
